Application and technology of mid-wave infrared lens

Introduction to Midwave Infrared Lens IR lens is medium wave infrared lens. It uses special optical glass material and uses the latest optical design method to eliminate the focal plane shift of visible light and infrared light, so the light from visible light to infrared light can be in the same A focal plane imaging, so that the image can be clear. In addition, the IR infrared lens also uses a special multilayer coating technology to increase the transmittance of infrared light. Therefore, a camera with an IR lens can monitor a longer distance at night than a camera with an ordinary lens, and the effect is better. 　　 In order to meet the needs of 24/7 surveillance, many places not only require cameras to complete surveillance tasks during the day, but also to present clear images at night. Moreover, in recent years, infrared cameras and infrared lights have been widely used, and the prices of day and night cameras and high-definition color cameras have dropped to a certain extent. This has also provided lens manufacturers with a large number of market opportunities. This is how the IR surveillance camera lens was born.
